| This release was created by: | |
| * Building a combined binary of `tailscale` and `tailscaled` | |
| * Using the build option `--extra-small` | |
| * Compressing the binary with UPX | |
| To use both programs, rename `tailscaled-OS-ARCH` to `tailscaled` and create a symbolic (`ln -sv tailscaled tailscale`) link. |
